Team - We have a requirement where we receive an email in dynamics from an outer system. We need to reply to this email from dynamics as an acknowledgement email, automatically. This email should be sent as a reply to this email so that the person receiving this email, in his outlook sees it as a conversation thread over the original email.
When I manually reply from Dynamics, it shows as a thread in the receiver's outlook. But we need to automate this.
We tried creating the new email with same subject/description/dynamics token number but it shows as a new email in outlook. We also tried setting the messageid and conversationindex in the email from the original email but then the receiver doesn't get an email at all.
We are working with Dynamics UCI. Any help would be appreciated.
